What is it?
The future. Chevrolet is not only the first maker to bring a serious series-production battery-powered car to the market, it has, arguably, come up with the most technically intriguing solution.
General Motors insists that the Volt is not a hybrid but an ‘extended range electric vehicle’, making it the first production battery-powered car that can promise not to leave the driver stranded at the side of the road.
GM's announcement on the inner-workings of the Volt's innovative and complex powertrain hit the headlines last week over just what the car should be classified as. Ignoring the semantics, GM will argue that the Volt’s unique layout is best placed to offer the potential of both a purely battery-powered commute during the week and pretty frugal, mostly petrol-powered, longer journeys at the weekend.
The car is based on GM’s new Delta platform, which also underpins the new Astra and Chevy Cruze. It uses the same basic McPherson suspension and the clever U-section Torsion beam axle. Unfortunately, the Volt’s back axle does without the Astra’s clever Watts link. The Volt gets also unique, lightweight wheels and specific Goodyear low-friction tyres.
What’s it like?
There’s virtually no noise when you press the illuminated start button and you only have to pull the (disappointingly awkward and clunky) shift lever into ‘D’ mode to make a silent getaway.
The smooth torque of the electric motors does a surprisingly good job of disguising the Volt’s 1715kg kerb weight. However, like the Prius, the Chevy seems to encourage the driver to flow along gently, rather than to push on.
This is probably a combination of the steady swell of torque, lack of gear changes, the silence of the drivetrain and the dash graphic counting down the distance to discharge.
Even under reasonable acceleration on the local freeways, the Volt’s battery-driven drivetrain mode remains relaxed and refined. There’s none of the audible strain of the racing engine and CVT ‘box that can blight the Prius.
